CACHE POLLER FOR PROVIDING TRAVEL PLANNING INFORMATION

摘要

Systems and techniques for travel planning are described. A travel planning system is queried with travel queries specifying parameters of trips. Answers to the queries are received from the travel planning system, and seat availability of flights in the itinerary information in the answers is predicted. Only those answers for which seats are predicted to be available are stored in a cached database for later use in answering user-specified queries.
